Title: Human pak65
Inventor: MARTIN GEORGE A
IPC: C12N9/12
Filed: 1996-01-05
Granted: 2008-10-07
Abstract: A novel humain serine protein kinase, human p21-protein activated serine kinase p65 protein referred to as hPAK65, and methods for its preparation and use are provided. Nucleic acids encoding hPAK65 and methods for their use in preparing hPAK65 as well as in preparing and identifying hPAK65 analogs are provided. Methods provided for the use of hPAK65 protein and its protein fragments, such as those that retain at least one hPAK65 activity, that include screening libraries of agents for candidates that modulate hPAK65 activity. Methods are provided to identify agents that modulate the interaction of hPAK65 with rho-like p21 GTPases, particularly rac1 and CDC42Hs binding to hPAK65 and subsequent activation of hPAK65 serine protein kinase activity, that modulate hPAK65 serine protein kinase activity, and that modulate hPAK65 effect on p21 protein GTPase activity. Such modulating agents can provide novel chemotherapeutic agents for treatment of neoplasia, lymphoproliferative conditions, arthritis, inflammation, autoimmune diseases, apoptosis, and the like, that are related to hPAK65 and p21 protein signal transduction pathways.

Title: Mixing apparatus
Inventor: FLOWER ARNOLD B
IPC: B01F7/04
Filed: 1997-07-11
Granted: 2004-05-04
Abstract: A mixer for mixing particulates is provided having a housing including parallel side walls and end walls arranged orthogonally with respect to the side walls, and a cylindrical curved bottom wall blending tangentially into the side walls and meeting the end walls, the bottom wall being curved about a longitudinal axis passing through the end walls. A mixing element has a shaft mounted for rotation about the axis and extends between the end walls. The element also includes a plurality of outer paddles, and a plurality of inner paddles to define a series of mixing zones spaced axially along the shaft. Each of the mixing zones includes at least one of the outer paddles angled relative to the axis to drive particulates in a first axial direction and at least one of the inner paddles angled relative to the axis to drive particulates in the opposite axial direction. As a result at least some of the particulates in a zone move firstly in the axial direction under the influence of the outer paddle and then in the opposite axial direction under the influence of the inner paddle, and the zones combine to effect mixing of the particulates.      The mixer can be used in a modular fashion by grouping several mixers essentially in side-by-side relationship in a common housing to increase the volume of the mixer.

Abstract: Electrochemical cells are made by coating the major faces of positive and negative plates with a layer of electro-chemically active paste, but leaving uncoated portions corresponding to single horizontal edge of the plates.  A cell unit consisting of a positive plate, a negative plate and a sheet of separator disposed between said plates, is assembled in such a manner that the horizontal edge of the positive plate is aligned opposite the uncoated horizontal edge of the negative plate.  Negative and positive connectors are attached to the horizontal edges of the cells in a circular motion.          The horizontal edge of the negative plate extends beyond the edge of the separator and the separator extends beyond the edge of the positive plate.  The horizontal edge of the positive plate extends beyond the edge of the separator and the separator extends beyond the edge of the negative plate.  The cell unit is assembled by spirally winding a single sheet of the separator and the negative and positive plates on a mandrel.

Title: Reconnaissance de la parole
Inventor: SIMONS ALISON DIANE
IPC: G06F19/00
Filed: 1996-03-07
Granted: 2002-01-22
Abstract: Système de reconnaissance de la parole qui est doté de valeurs de probabilité à priori (par ex. provenant de reconnaissances précédentes) indiquant dans quelle mesure les différents mots du vocabulaire du système de reconnaissance de la parole sont susceptibles d'apparaître dans le contexte particulier. Des "scores" de reconnaissance sont pondérés par ces valeurs avant qu'un résultat (ou des résultats) ne soit choisi. Ledit système de reconnaissance emploie également le "tri" si bien que les résultats partiels à faible score sont éliminés, de manière à accélérer le processus de reconnaissance. Pour éviter un tri prématuré des mots les plus susceptibles d'apparaître, des valeurs de probabilité sont appliquées avant que les décisions de tri ne soient prises. Un procédé permettant d'appliquer ces valeurs de probabilité est également décrit.

Title: Document registration apparatus with improved document drive capability
Inventor: DEBARBER CHRISTOPHER
IPC: B65H9/10
Filed: 1997-11-06
Granted: 2006-08-15
Abstract: A document registration apparatus for use with a conveying device for transporting a document along a path from an upstream direction to a downstream direction through a document registration position includes an urge roller positioned adjacent to the path, the urge roller being moveable between a first position contacting the document and a second position out of contact with the document. The urge roller is biased toward the conveying device. A  registration stop is positioned adjacent to the urge roller and the path, the registration stop being moveable between a first position where it blocks transport of the document along the path and a second position away from the path where it does not block transport of the document along the path. At times when the urge roller is in its first position and the registration stop is in its first position the urge roller is biased against the document by a first force thereby urging the document against the conveying device due to the first force so that the document is moved to, aligned against, and stopped by the registration stop at the document registration position. At times when the urge roller is in its first position and the registration stop is in its second position the urge roller is biased against the document by a second force such that the document is urged against the conveying device by the first and second forces so that it is moved from the document registration position in a downstream direction from the registration stop.

Abstract: A unique switching valve for use with a mufti-chamber adsorbent air and gas fractionation system for controlling the flow of fluid which comprises a valve housing including an inlet port, two outlet ports and an exhaust port and first valve and second valve members in the valve housing which are moveable between a first position and second position for alternately permitting and blocking fluid flow between the inlet port and the outlet ports and between the outlet ports and the exhaust port. The first and second valve members include means for permitting a predetermined controlled flow of fluid between the inlet port and the outlet ports and means for permitting a predetermined controlled flow between the outlet ports and the exhaust port which simplify the design and control of the switching valve by eliminating the need for separate repressurization and depressurization valves. A mufti-chamber adsorbent air and gas fractionation system utilizes the unique switching valve and comprises a pair of adsorption chambers adapted for air flow therethrough and periodic cycling between an adsorption cycle and a regeneration cycle where each chamber is alternately placed in communication with an inlet line which receives a pressurized air feed stream and an exhaust line maintained at a reduced pressure so that one chamber receives the pressurized air feed stream and is in the adsorption or drying cycle while the other chamber is simultaneously connected to the exhaust line and is in the reduced- pressure desorption or regeneration cycle.
